Add the International Monetary Fund to the list of economists, business leaders, and Wall Street executives warning of the damaging consequences of not paying America’s bills:

“The U.S. should raise its $14.3 trillion debt ceiling to avoid ‘a severe shock’ to the global economy, the International Monetary Fund has warned.”

“In an annual report card on U.S. economic policy made public on Wednesday, the IMF said the debt ceiling should be raised as soon as possible to avoid damage to the economy and world financial markets.”
